Abstract


This study was carried out to investigate the antioxidant effects of extracts from 9 species of forest plants in Korea. DPPH, ABTS, NaNO 2 , hydrogen peroxide radical scavenging activity and reducing power activity were evaluated to measure the antioxidant activities of plant extracts. As a result, Geranium thunbergii has been identified as the most effective antioxidant resource. Also, total phenolic content was highest in Geranium thunbergii (303.94±0.63 mg GAE/g) among 9 species extracts. Total flavonoid content was highest in Rosa multiflora (24.32±0.22 mg QE/g) and proanthocyanidin content was highest in Vitis ficifolia (279.00±4.58 mg CE/g) among 9 species extracts. In addition, the protective effect of plant extracts in H 2 O 2 -induced human dermal fibroblast (HDF) cell systems were also assessed. Significant protective effects in H 2 O 2 -induced human dermal fibroblast (HDF) cell systems were found in all plant extracts, especially in Geranium thunbergii. These results suggest that Geranium thunbergii could be a potential natural resource for antioxidant activity.
